



BreezeNET is a family of wireless products for Point-to-Point and Pointto-MultiPoint networking, optimized for outdoor usage, in adverse
environments and weather conditions.
The enclosure used by all the BreezeNET models is dust-tight and
water-proof. The degree of protection, rated with the IP scale, is IP 67.
An automatic heating system extends the operating temperature range
down to - 40 C.
The efficient cooling provided by metal tongues (no fan and no forced
ventilation) extends the operating temperature range up to + 55 C.
Indoor-Outdoor architecture simplifies installation and maximize
performances.
The Outdoor Unit shape makes life easier when mounting it on a pole.
Lightning protection is already included.

What does it mean IP 67?




IP stands for Ingress Protection
The rating s first digit e.g. IP54 relates to the ingress
protection against dust
The second digit e.g IP54 relates to the ingress protection
against water
IP 67 means:
1.
2.
No ingress of dust
Ingress of water in a harmful quantity shall not be possible when
the enclosure is immersed in water under defined conditions of
pressure and time
4
Water immersion test for IP 67 certification

Product features-version 4 (2.4Ghz only)
Long / Short Preamble Support - (BU Only)
Two different preamble types are defined: the mandatory supported Long Preamble, which
interoperates with the 1Mbps and 2 Mbps specifications as described in IEEE 802.11
standard, and a
Short Preamble, as described in IEEE 802.11b standard.
The Short Preamble may be used to minimize overhead and thus increase the data throughput
- Increase throughput in Short Preamble by 30%.
The BU supports (configurable parameter) long and short preamble frame format.
The Short Preamble is supported only by the IEEE 802.11b standard (High-Rate), and not by
the
original IEEE 802.11 standard. That means that stations using Short Preamble cannot
communicate
with stations that support only the IEEE 802.11 standard. By default, the BU is set to use the
long
preamble (for backward compatibility).
Short Preamble may be enabled only if all units support the IEEE 802.11b standard and can be
configured to support Short Preamble.
This parameter is available only in BU; the RB will identify the preamble type used by the BU
and will
use it as well.
The default is Disable
21
Product features-version 4 (2.4Ghz only)
MAC Address Association Control - (BU Only)
The Access Control List table is used to authorize / deny access to certain stations.
It is possible to add a specific RB MAC address into the Add/Delete MAC Address ACL.
The format should be XX-XX-XX-XX-XX-XX. The status of the entry is defined by checking the
Allowed check box.
Configuration utility -> Security button -> ACL Table -> Check the Add check box to add
the entry, and click the apply button.
The broadcast address FF-FF-FF-FF-FF-FF serves as a default entry to define the status of
addresses that are not defined in the list.
If the table is empty, access is denied to all addresses.
Max number of entries _128.
22
Product features-version 4 (2.4Ghz only)
802.11 WEP - 128-bit encryption key
The product supports the standard 802.11 WEP (40 bit encryption key) in both
authentication and data encryption.
In addition, an enhanced proprietary security system utilizing a 128-bit encryption key is
incorporated, to provide superior privacy.
The implementation was done by HW to avoid any performance degradation.
Wired Equivalent Privacy (WEP) is an encryption algorithm that protects authorized Wireless
LAN users against eavesdropping and is implemented in BreezeNET DS.11 units. It supports
key length of either 64 bits or 128 bits,including a 24 bit Initialization Vector.
WEP keys _ Defines the encryption keys used. Define each key by clicking the appropriate
WEP Key row and entering 10 (for 64 bits keys) or 26 (for 128 bits keys) hexadecimal
characters for each of the four keys. After clicking Apply, the WEP Key values are displayed
as zeros for security reasons.
23
Product features-version 4 (2.4Ghz only)
Proprietary Scrambling of data
The scrambling mechanism is another security measure that can be enabled or disabled
independently of the WEP mechanism.
It may also be used for simple to implement security without the administrative effort
associated with distributing and managing keys.
It is a differentiating element, disabling association of stations that do not have this feature.
The default is Disable.
